Evaluation of the Physical-chemical Characteristics and Biopharmaceutical Performance of Dilu-Cap: A Complete Line of Excipients for Hard-shell Capsules.

The development of an efficient formulation for hardshell capsules needs to consider pharmaceutical and biopharmaceutical aspects to assist in the careful selection of excipients, which are essential ingredients for the formulation's good performance. They ensure correct bioavailability, solubility, stability, dose accuracy (weight variation and content uniformity), and organoleptic characteristics. Given this, DiluCap was developed as a line of excipients so that the pharmacist can compound every capsule formulation with ease and trust in its final characteristics.

Compatibility of Gestrinone, Nimesulide, and Piroxicam in Pentravan for Transdermal and Transmucosal Application.

Transdermal products are intended to be applied topically but to promote the biological effects systemically, while transmucosal products have the same final effect but are to be applied on mucosa (for example, vaginal mucosa). The extension and velocity in which absorption occurs vary depending on the vehicle used, the active pharmaceutical ingredient and a broad range of other factors related to the formulation, patient, and environmental characteristics. Ready-to-use vehicles, such as Pentravan, with proven penetration efficacy for various active pharmaceutical ingredients, are paramount.

Characterization and Safety Profile of Transfer Factors Peptides, a Nutritional Supplement for Immune System Regulation.

Imuno TF is a nutritional supplement composed of isolated transfer factors (TF) from porcine spleen. It is composed of a specific mixture of molecules that impact functions of the biological systems and historically is linked to the immune system regulation. In this study, we demonstrate for the first time its proteomic analysis, nutritional composition, and safety profile in terms of mutagenic potential and acute oral dose (LD).

Always the Right Dose? Content Uniformity in Over 100 Different Formulations Tested.

There is still an evident need for nonsterile compounded medications for pediatric and elderly patients in cases where patients require dose adjustments or have swallowing difficulties. Pharmacists generally have the choice between compounding capsules or oral liquids. In daily pharmacy practice, extemporaneous capsules are from time to time seen as a better alternative to oral liquid medication, although various published studies indicate that weight variation and/or uniformity of content can be significantly out of specification for compounded capsules.

Compounded Orodispersible Films with Natural Ingredients for Halitosis: A Clinical Experience.

Halitosis can be described as unpleasant odors emanating from the oral cavity. It is usually associated with decomposition action of bacteria present mainly on the back of the tongue and periodontal pockets, and able to produce volatile sulfur compounds. We conducted a study at the Faculty of Dentistry, Federal University of Juiz de Fora and evaluated the therapeutic effect of two natural extracts, Camellia sinensis (green tea) and resveratrol in the form of oral polymer films, to control halitosis.

Delivering Resveratrol on the Buccal Mucosa Using Mucoadhesive Tablets: A Potential Treatment Strategy for Inflammatory Oral Lesions.

Background: Resveratrol is a polyphenol that has gained momentum in therapeutics in the last few years.

Objective: In this study, we hypothesised that resveratrol could act prophylactically and/or treat inflammatory lesions of the oral cavity after being delivered by two different formulations of buccal mucoadhesive tablets (F1 and F2, which differed in terms of viscosity agents used).

Methods: This hypothesis was assessed through permeation studies, to verify diffusion of the drug through the buccal mucosa using a porcine model to predict human in vivo behaviour.

The objective of this study was to evaluate the stability of 7 commonly used active pharmaceutical ingredients compounded in oral suspensions using an internationally used suspending vehicle (SyrSpend SF PH4): acetazolamide 25.0 mg/mL, baclofen 10.0 mg/mL, dipyridamole 10.

Ex vivo Skin Permeation Evaluation of An Innovative Transdermal Vehicle Using Nimesulide and Piroxicam as Model Drugs.

Background: The transdermal dosage forms presented a limited usage for a long time, for it was believed that the stratum corneum, the outermost layer of epidermis, made it impracticable the permeation of medications through the skin. Studies exploring this area came up with strategies to overcome this barrier; for example, creating a transdermal vehicle to facilitate the drug absorption.

Objective: This study aimed to evaluate a new transdermal vehicle through the comparison of its permeation profile and the profile of commercial products, using nimesulide and piroxicam, non steroidal anti-inflammatory drugs.

Transdermal Oxandrolone: Ex Vivo Percutaneous Absorption Study.

Background: Oxandrolone is a potent synthetic testosterone analogue that possesses strong anabolic property and weak androgenic activity. Apart of their clinical implicances, oral oxandrolone can potentially promote several adverse effects. It is known that the transdermal delivery of drugs may represent a means to avoid or minimize oral adverse effects Thus, the objective of this study was to evaluate the permeability of oxandrolone in human skin on a preliminary basis for possible future determination of the transdermal route as an alternative to oral treatments.

Permeation profiles of resveratrol cream delivered through porcine vaginal mucosa: Evaluation of different HPLC stationary phases.

Trans-resveratrol affects biological systems in a multitude of ways, but its oral bioavailability is remarkably poor due to in vivo metabolization. This drawback has fomented the development of new strategies for systemic delivery, such as transmucosal delivery via the vaginal route, which is our main focus here. In this sense, our pioneering study purposed to evaluate the trans-resveratrol permeation efficacy through this route.

Studies with emulsion containing trans-resveratrol: in vitro release profile and ex vivo human skin permeation.

Resveratrol is a phenolic compound that has been widely studied in the last years because of its extensive pharmacological properties. It also has physicochemical properties that are adequate for diffusion through the human skin. An analytical method by high performance liquid chromatography was developed and validated for its determination in transdermal emulsion, as well in receptor media and skin layers.

Pharmaceutical development of enteric-release hard gelatin capsules in the compounding setting.

Enteric coated capsules are characterized by their resistance to dissolution in low pH environments, such as the stomach, and by their rapid disintegration in a higher pH environment, such as the intestine. The surface of hard gelatin capsules is usually smooth and nonporous, which limits their coating efficiency. We developed a simple, quick, and easily reproducible compounding preparation method for enteric-release hard gelatin capsules.
